I have had this one for years and it probably is from the 50's to 60's.   The prismatic double pictures include Christ on the Cross with the second image being Christ Ascending.  The other pair is a Jesus profile with the second picture being The Last Supper.  I did plug the clock in and it runs.  I did not test it for accuracy and the hands have some bends to them that need attended to. 

The shipping cost is high due to the overall size (29x16x4) on the frame.  I am planning for a tight box (31x18x8) to avoid the Oversized charges from UPS and USPS.  It will require lots of work and a custom sized box.
